BIT HAMMER AND JOINT BREAKER.

Application filed December 11, 1922.

To all wk/)m t may concern.'

Be it known that I, MYRoN BRANDEBERRY,

a citizen of the United States, residing at Bloomdale, in the county of Wood and State of Ohio, have invented new and useful 1mprovements in Bit Hammers and Joint Breakers, ot which the following is a specification.

This invention relates to a bit hammer and joint breaker, the general object ot' the invention being to provide a hammer carrying member and an anvil carrying member, with mea-ns for reciprocating the hammer member to bring one hammer thereon against the bit on the anvil member andfor oscillating the hammer member to bring another hammer against an article on the anvil member.

Another object of the invention is to providc means whereby both members may be moved along a track,y with means for connecting the two members together by a hexible member which is wound upon a drum on the hammer carrying member.

A further object of the invention is to provide means whereby different tools can be placed on the hammer carrying part ot the hammer member.

The invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like reference characters denote like or corresponding parts through-v out the several views, and in which Figure 1 is a plan view ot the invention.

Figure 2 is a side- View thereof.

Serial No. 606,149.

Figure 1() is a detail view of the removable hammer carried by the three-armed lever.

Figure 11 is a detail perspective view of a chisel supported on the hammer end of the three-armed lever.

Figure 12 is a detail longitudinal sectional view through the hammer end of the threearmed lever with the removable hammer supported thereby.

In these views, 1 indicates a track, preferably of semi-circular sha-pe, or substantially so, the top ot which being formed with ratchet teeth 2, excepting t-he front end, which is left plain. The sides of the track are grooved to receive the tongues of the hammer carrying member 3 and the anvil carrying member 4, so that these members are movably mounted on the track. rfhe member 3 can be locked to the track by the locking means 5 and the member 4- is provided with the dogs 6 which engage the ratchet teeth and act to hold the member 4 against movement in one direction on the track. Member 3 carries a drum 7, provided with ratchet means 8, and a chain 9 is connected with the drum and with the member' 4t. Thus the two members are connected together by the chain. A stem 10 fits in a socket formed in the member 3, said stem having a spherical head which engages a socket formed in a three armed lever 11, so that the lever is moivafbly mounted on the stem. The arms 12 and 13 form handles, the arm 13 being vertically arranged, and the arm 14 has a hammer formed at its end, as shown at 15 and this arm has a dove-tail slot 16 in its under part to receive a. hammer 17, which is provided with a dove-tailed end to engage the slot. A set screw 18 holds the hammer 17 in position. A chisel 19 is adapted to Fit over the hammer 15 and to be held thereon by a set screw 20 and a wrench 21 is also adapted to have its sockerted part tit over said hammer and to be fastened in position by the set screw 22.

The jaws of this wrench form a circle when 14 against the bit on the anvil member, the

hammer being guided by the handle 12. r1`his hammer is useful in shaping the cutting ends of bits. When the lever is rocked the under hammer gives a vertical blow and is `useful for shaping the bodies of hits. The

chisel will be used for cutting grooves in the bits for the water to pass through and; the wrench is used for uncoupling well pipes and the like as shown in Figure 5.

In using the aforesaid assemblage of elements as a bit hammer, a bit is placed on the anvil carrying member with its cutting surface directed toward the reciprocating hammer carrying member. After so arranging the bit the crank 211 is rotated toward the anvil carrying` member, before starting the motor, not shown, whereupon the anvil carrying member is disposed a suiiicient distance from the outward limitation of the thrust of the hammer 15 to procure the desired' impact on the face of the bit. With these elements so arranged, the bit is held on the anvil by one attendant and the hammer is guided toward and in contact with the face of the bit by a second attendant through the instrumentality of the arm 12, as the crank continues to reciprocate the hammer carrying `memberl As the anvil carrying member is disposed so the face of the bit lies suiciently within the range of the reciprocating hammer to produce the proper impact of the hammer thereagainst as it reaches its outward stroke, the blow on the anvil is not severe and is taken up through the dogs 6 which engage the teeth 2 of the track 1.

I When the hammer is used to shape the shank or other portions of the bit the hammer 17 is secured to the arm 13 and the arm 14 is rocked in a vertical plane above the bit through the instrumentality of the reciprocating rod 25 which is released from the hammer carrying member and fastened to the arm 13. Prior to so connecting the rod 25 to the arm 13 the hammer carrying member is secured to the track 1 by the locking means 5 so it will remain in proper fixed relation to the anvil carrying member to permit the hammer 17 to repeat its blows on the bit as the rod 25 continues to reciprocate. During this movement the attendant guides the arm 14 through the instrumentality of the arm 13.

In using the elements of this invention to break the joints of well pipes, the wrench 21 is engaged with the section of pipe to be turned with the hammer carrying member disposed on the track 1 in close proximity to the curved portion thereof and at the desired outward limit of thrust of the reciprocating rod 25 and, upon causing the crank to be rotated by the motor, not shown, the reciprocating rod 25 will turn the section of the pipe to which it `has previously been fastened and return the' wrench for subsequent grips on the pipe during kthe reciprocations of the rod 25,

In order to permit the hammer carrying member to reciprocate in a straight line while the hammer, arm attached thereto travels concentrical with the well pipe, the proper degree of slip is permitted through the fastening means between the wrench and l arm 141.

In order to utilize the hammer carrying member and anvil carrying member to try pipe joints, that is to ascertain whether or not the pipe joints are tight, the hammer carrying member, with the arm 11 fastened to the pipe through the instrumentality of the wrench, is drawn toward the previously secured anvil carrying member through the instrumentality of the chain 9 and ratchet mechanism 8.

Having thus described my invention what I claim as new is 1. A device of the class described, comprising a hammer carrying member, an anvil carrying member, a hammer carryingflever movably mounted 0n t-he hammer carrying member, handles on the lever, an actuating member and means for connecting the actuating member to the hammer carrying member to reciprocate or rock it.
